摘要: 实验数据显示,钛板在平行和垂直轧制方向上的屈服应力和R值有如下的关系:若某一方向的R值比另一方向的大,则此方向上的屈服应力也比另一方向的高。本文根据塑性理论导出了一个公式,试图从理论上对此关系加以描述。统计处理表明,此式与实验数据吻合良好,并对此式的适用范围和应用价值进行了简短的讨论。
关键词 钛板屈服应力R值    
Abstract:An attempt was made on the quantitative prediction of the relation-ship batween yield stress and R-value along the directions parallel and perpendicul-ar to rolled Ti plate based on analysis of the previous experimental data. It is sh-own that the yield stress along one direction and another is synchronized withR-value. Based on the theory of plasticity a formula of σ_(1s)/σ_(7s)=[1+1/R_2)/(1+1/R_1)]~(1/2)was proposed. In statistic estimation, the calculated results after the formula are inbetter agreement with the experimental data. The availability of this formula wasbriefly discussed also.
